HYDROCARBON-BURNER AND TORCH ATTACHMENT.

Specification of Letters Patent.

Patented July 3, 1906.

Application. filed J l 3,1905. Serial No. 268,151.

To all whom, it may concern:

Be it known that I, ELMER VICKREY, a citizen of the United States, residing at Green Oak, in the county of Bureau and State of Illinois, have invented certain new and useful Improvements in Hydrocarbon-Burners and Torch Attachments, of which the following is a specification.

This invention relates to hydrocarbonburners and torch or pilot-light attachments therefor, and has particular reference to such as are intended for use in steam motor-vehicles in which kerosene is employed as fuel.

The novel features of the invention reside more particularly in the construction of the torch or pilot-light attachment, the principal object of the invention being to provide an improved attachment of this character in which kerosene may be em loyed in the torch or pilot-light as well as in t e main burner.

Another object of the invention is to pro vide a burner of the character specified with means for quickly and certainly igniting the same.

A further object of the invention is to so construct a pilot-light or torch attachment that its operation will be noiseless and unaffected by wind, low temperature, or other conditions which are known to interfere with the satisfactory operation of attachments of this character now in use.

l/Vith these and other objects in view the present invention consists in the combina tion and arrangement of parts, as will be hereinafter more fully described, shown in the accompanying drawings, and particularly pointed out in the appended claim, it being understood that changes in the form, proportion, size, and minor details may be made within the scope of the claim without departing from the spirit or sacrificing any of the advantages of the invention.

In the drawings, Figure 1 is a horizontal section of a burner with parts broken away and showing the construction of the pilotlight attachment. showing the lower part of an automobileboiler with burner attached. Fig. 3 is a plan view of the pilot-light mixer. Fig. 4 is a plan view of the pilot-light burner, and Fig. 5 is a central vertical section of the gas-chamber of the pilot-light.

Like reference-numerals refer to corre,

Fig. 2 is a vertical section i needle-valve 28.

in its preferred relation to a vertical-tube boiler 2. This burner consists of the circular casing 3, having the bottom plate 4 and the perforated partition 5, dividing the said casing into a gas-chamber 6 and a combustionchamber 6*. Kerosene is admitted to the burner from a fuel-tank (not shown) through the relatively large pipe 7, which passes through the gland 8 in the casing 3. The pipe within the casing is preferably bent into a curved form, as shown, and then into relatively large vaporizing-coils 9. The fuel from the coils 9 passes out of the casing 3 through pipe 10, which passes through gland 11. This pipe 10 is bent downward at 11 and enters the mixer 12, inwhich the vaporized fuel is mixed with air in the well-known manner. The mixed fuel-vapor and air passes upward through the perforation 13 in the partitionplate 5 and are burned within the combustion-chamber 6*.

To effect the vaporization of the kerosene and its subsequent ignition, I employ a pilotlight or torch to which kerosene is supplied from a relatively small fuel-supply pipe 14, having oontrolling-valve 15 therein. The pipe 14 enters the casing through gland 16 and is bent into the relatively small vaporizing-coils 17, preferably located within the coils 9. Below the coils and preferably located near one side of the casing, as shown, is a gas-chamber 18, having circular and concentric inner and outer walls 19 and 20. The chamber 18 is provided with the bottom plate 21 and the upper slotted plate 22, above which the fuel admitted to the torch is burned. The upper and lower plates of the gas-chamber 18 are secured in place bymeans of the rods or bolts 22*. Located below the gas-chamber 18, but in communication therewith through opening 23, is the U-shaped mixing-chamber 24, preferably secured there to by a screw 25, passing through opening 26. Fuel admitted through supply-pipe 14 is vaporized in coil 17 and passes downward through pipe 27, located within the opening in the inner wall 19 of the gaschamber. The pipe 27- communicates with the mixer 24, such communication being controlled by the The kerosene-vapor after being mixed with air in the mixer 24 passes into the gas-chamber through opening 23 and through the slots 29, where it is burned sponding parts throughout the several views. about the coils 9 and 17.

In the drawings the main burner l is shown i The operation of the burner and pilot-light attachment is as follows: By the use of the flame of a small pocket-torch, such as is commonly used for the purpose, inserted through an o ening (not shown) in the casing 3 the smal vaporizing-coils 17 of the pilot-light attachment is heated until they are a dull red, which requires about one minute. The controlling-valve 15 is then opened slightly and a small amount of kerosene is admitted to the heated coils. This kerosene is immediately vaporized, and the resulting vapor mixed with air passes upward through the slots in the top of the gas-chamber 18 and is ignited by the flame of the pocket-torch. The flame of the pilot-light burner will, in about two minutes longer, heat the coils 9 of the main vaporizer to a dull red, and the liquid-supply of the main burner may then be turned on. 1

By the use of the improved pilot-light attachment above described it is possible to produce a flame above the main burner of full heating strength in about three minutes from the time heat is applied to the pilot-light vgporizer and without any smoke, noise, or 0 or.

WVhile I have described my burner as particularly applicable for burning kerosene, it is to be understood that it is also adapted I claim as novel, and desire to secure by Letters Patent, is

A hydrocarbon-burner and pilot-light attachment comprising a casing, a main burner arranged within said casing, a supplemental burner likewise located in said 1casingh, a fuel= su ly i e for su plying e to t e main bu l iier alh d provide d with coils which lie con centrically above the supplemental burner and a fuel-supply pipe formed of smaller tub ing than the main supply-pipe, one end of which is connected to a source of fuel-supply and the other end of which passes through a central opening formed in the supplemental burner and is connected to a mixing-chamber therebelow, said fuel-supply pipe having coils smaller in diameter than the coils of the main fuel-supply ipe, said coils being arranged concentrica ly within the coils of said main pipes.

In testimony whereof I afliX my signature in presence of two witnesses.
